Good list. I would probably make overall accuracy a 1a/1b thing with rodgers/brady... and play action is defnitely brady. He is the KING of play action. Also cutler has got to be number one for throwing power.

I think the main difference between throwing power and pure arm is that throwing power is basically how far with accuracy one can throw when using their whole body, footwork, and mechanics to put power into throw (i.e. being fully planted for a throw).

Pure arm is when you have to make a throw without the great mechanics, planting of the feet, etc. I.e., how well you can throw the ball with just your arm.
